Microsoft’s Windows 10 is a mess of UI. Its a mixture of Metro, Aero and new Fluent Design. With Fall Creator Update, Microsoft has started adding new design language to the different part of the OS. Microsoft enthusiast Rafael Rivera has leaked screenshots from a Redstone 4 build where Microsoft tweaked how the settings app looks. We already know that Microsoft has changed the design of the Start and Action Center and found proofs of bringing the new design language to the taskbar. From the tweet, we can figure out that the layout of the settings app has been changed. Microsoft also added Acrylic and Reveal to the sidebar in the settings ‘ pages.
